the end faces of the brackets the detachable member takes all of the wear of the spindle. When worn this member costing but little may Vbe quickly replaced and the guideway may thus be restored to its original condition, position and dimension.

With the above and other objects in View the invention may include the features of construction and operation set forth in the following specification and illustrated in the accompanying drawing.

Y In the accompanying drawing annexed hereto and forming a partv of this specification, the invention is shown embodied in a spool winding machine for textile yarn of standard formV but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon for that purpose.

In the drawing Fig. 1 is a plan View of a por` tion of a spool winding machine having the improved spool supporting bracket and guide shown in position thereon; and

Fig. 2 is a side elevation of the parts shown in Fig. 1 partly in section.

Briefly, and in its preferred aspect, the invention may include the following principal parts; first a spool supporting bracket of the general form now used in standard winding machines,

Vthe spool supporting end or ends only being modified; and second, a detachable member secured to the end face of the bracket, this member preferably being moulded and of such material as will not require lubrication to be supplied .thereto and formingrwith the end face of the bracket a substantially vertical slot or recess on each side of the bracket within which the spindle ends of spools being Wound may extend and be retained while movable upward as the spool becomes illed withryarn. The recess formed by each flange is suiciently deep to accommodate the spindle en-d of a spool and with .the opposite recess of an adjacent bracket will prevent endwise movement of a spool. Y

Referring more in detail to the figures of the drawing there is provided a spool supporting bracket lil attached as shown in the usual manner to the frame members. it of a winding machine. It will be understood that there are a plurality of these brackets lil disposed parallel to each other and uniformly spaced longitudinally of the machine. The winding machine may be of any standard form for winding, twisting, doubling o1' spinning textile yarns and each bracket Il] may 5 Claims.

This invention relates to textile winding machines and particularly to machines for winding silk or other yarn upon spools having flanges at opposite ends and the spools having also a central spindle the ends of which extend shortly` behind the flanges.

An object of .the present invention is to provide an improved spool supporting bracket for winding machines which may be cheaply made and which will provide an oilless bearing surface for the spool spindle ends during the winding operation.

Another object of the invention is to provide bracket which when worn or damaged may be removed and another end piece substituted therefore at a minimum expense.

Another object of the invention is to provide bearings for the extended spindle ends of the bobbins that will be non-metallic and thus entirely rust proof so that no rust will be formed that might be transferred to and damage the yarn being woun-d upon the bobbins.

And finally it is an object of the invention to provide a rigid moulded fibre member for the end piece of a spool supporting bracket having flanges thereon extending laterally and forming with the end face of the bracket substantially vertically disposed recesses or slots within which the spindle ends of the spools may ride upward as the spools flll with the yarn and be retained during the winding operation against lateral movement.

A feature of importance of the invention and which enables the above objects to be accomplished is that the spool supporting ends of the brackets of a winding or twisting machine are surfaced so that in their operative positions the end faces of the brackets will be in a substantially vertical plane parallel to the longitudinal members of the winding machine. This surface preferably has a central groove or shallow recess which serves as a supporting surface for a detachable member having the central web of the member entering the groove or recess. This detachable member is preferably of vmoulded fibre requiring no lubrication or may be of any wellknown oil-less metal bearing. This member has oppositely disposed laterally extending flanges which are spaced from the end face of the bracket and which form with the end face the necessary guideway or space for the spindle ends of the spools being wound. As the win-ding pressure is always against the inner surface of the flange during the winding operation and away from be similar to the others. For that reason but one pair of brackets I for supporting a spool I2 is shown.

Below the brackets I are traverse rod supporting brackets I3 having rollers I4 on which a traverse bar or rod I5 may reciprocate. Supported below the brackets I@ and I3 is a driving shaft I6 having friction wheels II adapted to engage and rotate the individual spools I2. In the form of machine shown in the drawing the friction wheels |'I directly contact the yarn being wound which is supplied to the spools I2 from any position (not shown) and passes over a guide I8 on the traverse bar I5 prior to being wound on the spools.

Each of the spools I2 is provided with central spindles having ends I9 extending from each end flange of the spool. It is by means of these extensions I9 that the spools I2 are held properly positioned during the winding operation,

The end face 20 of each bracket I0 is finished by being milled or planed so that in position this surface is vertical and substantially parallel to the longitudinal axis of the machine. Also formed on this end face is a shallow and narrow slot or recess 2| extending the full vertical length of the surface and disposed centrally thereof. Secured to this end face is a T shaped member 22 preferably having a central web portion entering the groove or recess 2|. Laterally extending flanges 23 of the member 22 extend parallel to the end faces 20 on opposite sides of the groove or recess 2|. There are thus formed on oppositer sides of the brackets I9 substantially vertical guideways 24 within which the spindle extensions I9 may enter and guide and support the spools I2. With the spool I2 disposed as shown in Fig. 2 and with the driving wheel I'I rotating upon the axis and in the direction as shown the pressure. of the extension I9 during the winding operation will be against the member 22. All wear due to this pressure will occur on the member 22 rather than upon the end faces 20 of the brackets I0. By replacing the members 22 when worn the spools I2 will be properly guided at all times without replacement of the complete brackets I0.

The members 22 may preferably be formed of integrally moulded material not requiring subsequent machine operations. Textile bres or fabrics moulded in a phenolic condensate such as Bakelite or other well-known composition may be used. Preferably a composition is chosen which will not require lubrication to be periodically supplied. Metallic, or metallic and graphitic compositions are also suitable. In any case the members 22 are durable and rigid enough to be secured to the brackets by several screws 25 extending through their central webs and being threaded into the forward end faces 2D of the brackets I0.

I claim:

1. A spool bracket for winding machines having at its spool engaging end a moulded bre bearing member detachably secured thereto and forming with the end face of said bracket oppositely disposed vertically inclined recesses within which the extended ends of adjacent spool spindles may be disposed during the winding operation.

2. A spool bracket for winding machines having at its spool engaging end a moulded fibre bearing member detachably secured thereto and forming with the end face of said bracket a vertically inclined recess within which the extended end of a spool spindle may be disposed during the winding operation.

3. A spool bracket for winding machines having at its spool engaging end a flat surface, a fibre bearing member attached to said end of the bracket having a laterally extending flange thereon, the flange forming with said end face a substantially vertical recess within which the extended end of a spool spindle may be disposed during the winding operation.

4. A spool bracket for winding machines having at its spool engaging end a detachably secured bearing member, said member having laterally extending iianges thereon spaced a short distance from the end face of said bracket whereby the extended spindle end of a spool may be disposed Within the recess between said bracket end face and a flange, a central web portion on said member, and securing means for said member passing through said web portion.

5. A spool bracket for winding machines having at its spool engaging end a detachably secured fibre bearing member, said member having a central portion engaging and secured to the bracket within a slot provided in the end face thereof and flanges formed on said bearing member forming substantially vertical uniformly wide recesses on opposite sides of the bracket, whereby the extended ends of spool spindles may engage therein during the winding operation.
